Isis and Osiris

Age: Unknown
Race: Unknown

Their appearance always changes, and they never choose one place to settle down. They are the only living tuners in Eirian, and they known to be sisters, however, nobody really know for certain.

Their age is unknown, but certainly over 1200 years. As tuners, they can re-tune their body as they like, and they never age.
Both of them are wanted in each land of Eirian, people are hunting them, because they fear that they would open the portals between words (even though they have no intentions to do such things).

The only part of their body that they cannot tune is their tuner tattoos on their back. Those are permanent, and cannot be undone, so they have to hide their backs to make sure nobody recognizes who they really are.
